GLASSWARE-FINISHING MACHINE.

Specification of Letters Patent.

Patented Oct 8, 191 3 Application filed May 2, 1910. Serial No. 558,936.

To all whom it may concern:

Be it known that we, JAMES H. DEAKIN, residing at Marion, Indiana, andHENRY SGHNELBACI-I, residing at Charleroi, Pennsylvania, have jointlyinvented certain new and useful Improvements in Glassware-FinishingMachines, of which the following is a s ecification.

(gur invention relates generally to apparatus for finishing such glassarticles as lamp chimneys, and is in some respects an improvement 11 onthe invention in the patent of Sehne bach No. 842,426 of January 29th,1907.

The primary object of the invention is to automatically handle the snapsor holding devices for the articles, and to generally improve theconstruction and operation of such finishing machines.

We have illustrated the invention as applied to a lamp chimney machine,in the accompanying drawings, wherein,-

Figure l is a plan view of a graduated series of furnaces and themachine for carrying the articles, and Fig. 2 is a front elevation ofthe machine. Fig. 3 is an end elevation; l i 4: is a section of a snapor chimney hol ing tool and the supporting means for the same, and Fig.5 is a section and elevation showing the holder in the act of returningto its initial position in the machine.

In workin some kinds of glassware it is found desirable to have anoperator lift the articles and perform certain operations by hand. Forexample, on account of the irregularities of consistency in the firesoftened ends of lamp chimneys, it is often more satisfactory to crimpthe ends of the chimneys by hand operation. Our invention providesmechanism to automat cally take up lamp chimneys at one end of agraduated heating furnace, pass them in order through the variousheating zoncs, automatically discharge the chimneys when finished, andreturn the holding tools or snaps back again to the initial point to bereloaded; in the meantime the machine allows the snaps containing thechimneys to be lifted oil the carrying machine at any point, and to befinished by hand, after which the machine itself again picks them up anddischarges the finished chimney from the snap, and re turns the snap tothe starting point. Of

course, it will be understood that the improvement by which the chimneysare automatically discharged and by which the snaps are automaticallyreturned and opened to receive a new chimney, are equally applicable tothe form of machine in which the crimping or other finishing operationis antomatically performed by the machine itself,

in said Schnelbaehs former patent.

7 1n the accompanying drawing we represent at 10 a furnace having aseries of chambers 10,' 10, etc, heated with successively varyingdegrees of heat, and furnishing means to gradually bring the end of thelamp chimney which has been cut off, into proper plastic state forcrimping, so. that it arrives at the osition of the crimping machine 11,with its ends properly heated.

In front of the furnace, mounted on standards 12 and 13, we provide acontinual trateler which may consist of a chain 14 riding upon a guideplate 15, driven by sprockets on the shafts 1G and 17 by any convenientmeans as by pulley and belt 18. This chain carries a series of forks 19in which fit the handles of the snaps 20 (shown in detail in Fig. l).The snaps are made so as to be opened by a sim ile motion, as by pushingin the internal rod 21, which operates a slidinghcad 22 to open andclose the jaws 23 pivoted to the hollow head 2-1:, thereby clasping thechimney C. Normally the clamping arms 23 are held in closed position bythe relractile spring 25. As the snap containing the chimney movesforward on the rail 15 the rollers 31 revolve it, and when it arrives atthe position of the incline 26 as shown in Fig. 2, this incline liftsthe snap out of the forks l9 and the longer arm 19 of the fork 19 pushesit up beyond the retaining spring 26 until it rests on the raised track27. The operator then lifts the snap and chimney, lays the handle in therest :28, which is in line with the revolv ing tool 29 of the crimpingmachine 11. It will be understood that the chimney is given the beadededge or so-callcd crimp top by being pushed against the knives of thecrimping tool 25'. The operator then lays the snap on the inclined 'uiderests 30, which, by means of the rol ers or buttons 31 on the snaphandle engaging'the inclined guides 30, rights up the snap in positionto again drop into forks 19, as they pass down track 15. The forwardmovement'of the long prong 19 of the fork brings the snap back to thebottom notch, of the fork, as shown to the right of Fig. 2, in whichposition the snap passes under the guide 33 and is 'carriedbackto theinitial position, retained in the forkinverted, by the guide 33,-as willbe evident from inspection of the drawing. Meantime, as the snap passesover the, sprocket a cam34 mounted on a frame 35 attached to standard13, engages 1 the "stem 21 of the snap which is thereby pushed inward,and the chimney is released and drops into a proper receptacle, such asa traveling belt carrier 39. The rest 28 and the return guide tracks 30may be conveniently supported by standards 36 and crossbar 37 as shownin Figs. 2 and 3. As the empty snaps on the return guide rail 33 arriveat the position shown at X at. the left of Fig. 2, the, cam 37 engagingthe stem 21 of the snap opens the jaws 23 and an attendant'places a newchimney therein, the

operation above described being thereupon repeated. 1

It will be understood that our invention is not confined to anyparticular form of holder for the glass article, or mode of operatingthe same, nor. to any particular means for re-adjusting the position ofthe snaps after they have been picked up and pgandled and againdeposited on the rests.

Having thus described our invention and its use,'what we claim is thefollowing:

1. A finishing machine for glass articles having a series'of holders forthe articles, mechanism to' carry the articles and to open and close theholders in the carrier at two points of their travel, and mechanism toautomatically release the holders from the carrier at one point of thetravel.

2. A carrier machine for finishing glass articles, comprising acontinuous traveler, a holder for the articles mounted on the traveler,and means to temporarily release the holders and to open and close theholders at predetermin d positions when on the traveler, substantiallyas described.

3. A finishing machine for glass articles having a continuoustravelingcarrier, a se ries of holders bodily removably mounted on the carrier,means to lift them out of the traveling carriers and. means tore-adjusttheir position and reinsert them in the travcling holders, when placedagain on the carrier. I

4. The combination of an endless carrier chain having forks,self-closing snaps m. the forks, a cam arranged to open the snaps andmechanism to remove and then again aline' and. place the snaps in saidforks when replaced on the carrier chain, substantially as described.

5. The combination with a furnace having a graduated series of heatingchambers, of mechanism to carry glass article'sthrough the heating zonesin succession, holders and supporting means for said glass articlespermitting of the holders being'removed,'and means operating inconjunction with the holders and supports, after replacing the holdersthereon to discharge the articles at a predetermined point.

6. A lamp chimney. finishing machine having mechanism to support andtranslate and operate a series of snaps, with provision at onepoint ofthe path of motion, to temporarily release the snaps, and said movingmeans being designed to again take up the snaps when replaced thereon aneject the articles therefrom and return the empty snaps to initialposition, substantially as "described.

7. Apparatus for fire finishing glass articles comprising a continuousautomatic carrier provided with holders for the articles, and means totemporarily eject the holders'fora-hand' operation and then to returnthem to place in the carrier, when replaced ;on the carrier.

. Apparatus for finishing glass articles comprising 'a travelingcarrier, holders for the articles remova-bly mounted on the earrier, andmeans for retaining the holders on the carrier in its return travel,when replaced on the carrier.

9 In apparatus for finishing glass articles, a traveling carrier for thearticle, a series of holders for the article removably supported on thecarrier, and mechanism on the carrier for picking up'the holders andplacing them in operative position thereon automatically.

In testimony whereof we have hereunto signed our names in the presenceof the two subscribed witnesses.
